To all whom 'it may concern.: 4

Be 1t 'known that I, Jenn' donne, a citizen of the United States, and ident el? it and useful In'iproveinonts in .ll ,infox'ccd- Concrete FloorConstruction, ol. which the followingis n specification, containing :1full, clear, and exact description, reference be 'had to thea'ccompanyingdrawings, 'forming a art hereof.

'i' y invention relates to n reinforced concrete floor construction, theohiiA of any invention being-st: to materially inroepen the cost 'ofreinforced concrete flooring; fnd

to greatly increase the cnsile srrcngth or' 'the i y span or slab offlooring` between the door beams; 3rd: todo a'way with iihe r'iwng ofclnclers, or the like, which 1s nsua ily empl' 1n4 the construction ofconcrete floor:

floor sleepers are arranfrcd .in die upper poi tion of the concretelloorin` to 'icrfe tl )urpose of guides for thc top su .ce of ooring,and to provide means for eef. 1 the Wooden ilooring to the concrei eminstreel tion.

To the above purposes, ray invention ce sists in certain novel .ientureeof consirucion and arrangement of parte, 'which will be lhereinaf'be'rmore full eet forth, pointed on in the claims, and il ustrnled in 'the.acemn panying drawings, in which Figure 1- is a cross section mirenhrough a portion of a Span or Slob of concrete licor- .ing constructedin accordance with injf invention, and showing a part o5 the renderne:nent without the surrounding body or' con crete; Fig. 2 is a Sectionhalfen egiii'noninnitel on the line 2%2 of Fig. l; Fi is n perM secti-Ve View of a stanchion or reinio or sleeper support l make use ofin c ing out my'iniention; Fig. fl is a cra tion of the reinforcementneed for .mining one of the beanie which supports izhc floorconstruction; Fig. 5 is :i vcriical eretico. taken on the line 5-5 oi'Vig, l.
